If I receive this error msg in Linux Mint 14, codename (Nadia) ''Error mounting system-managed device /dev/fd0: Command-line `mount "/media/floppy0"' exited with non-zero exit status 32: mount: /dev/fd0 is not a valid block device'' it means that the floppy driver is loaded as a module. You can blacklist this module so it doesn't get loaded:

My new PC - running "Nadia" since a few weeks - too shows the "Unable to mount floppy disk" after logging in. Following Brahim's tip, I however get the error that the "Module floppy does not exist in /proc/modules".

I want to track this thread. I am unable to mount my floppy drive. I get the message also but do not know how to interpret it. My floppy is enabled in the bios. Any help is appreciated. Linuxmint 14 Mate
